Durability of Ag-TiO(2) Photocatalysts Assessed for the Degradation of Dichloroacetic Acid

Menendez-Flores, Victor M.; Friedmann, Donia; Bahnemann, Detlef W. (New York : Hindawi Publishing Corporation, 2008)

The stability of Ag-TiO(2) photocatalysts was examined for the photocatalytic degradation of dichloroacetic acid (DCA) as a function of the recycling times. The photocatalytic activity was investigated by measuring the ...
